Complete question is;
What is true of synthesis and decomposition reactions?
A) Synthesis reactions require more energy than decomposition reactions.
B) Synthesis reactions produce more products than decomposition reactions.
C) Synthesis reactions are the opposite of decomposition reactions.
D) Synthesis reactions have fewer reactants than decomposition reactions.
Answer:
C) Synthesis reactions are the opposite of decomposition reactions.
Step-by-step explanation:
